Equipment Details
Product Name: High Level SafetyCor Portable Sign Stand
Description:
The High Level Safety or portable sign stand is a lightweight sign support made up of 44.5 mm (1.75 inch) square "X-Tube" PVC extrusions. The X-Tube uprights slip into 57.2 mm (2.25 inch) perforated tube steel sockets welded to a support base. The support base is made up of 50.8 mm x 50.8 mm x 4.8 mm (2 inch x 2 inch x 0.19 inch) thick steel angle iron. The tested sign stand system featured a two-high arrangement of 914 mm wide rectangular signs made of 10.2 mm (0.40 inch) thick "SafetyCor", an unfilled polypropylene copolymer corrugated plastic sheeting material. Each sign is bolted to the uprights with four 7.9 mm (0.31 inch) diameter ASTM A307 hex fasteners and special 38.1 mm (1.5 inch) outside diameter rubber encased flat washers that increase the bearing area and help to prevent sign damage when the stands are stacked. When deployed the bottom of the lowest sign is nominally 1516 mm (60 inches) above the ground, and the overall height is 3662 mm (144 inches) to the top of the highest sign. As tested, the stands weighed 36.1 kg (80 pounds), and had four 18 kg (40 pound) sand bags as ballast. The four bags were placed at the ends of the supports.
